Rance is a brutish and perverted warrior that makes a living from several paid jobs he gets from the local Keith Guild in the town of Ice in the Free Cities Alliance, along with his relatively recently purchased and faithful slave Sill Plain.
One day, he receives a request to investigate the missing case of a noble girl from the majestic Kingdom of Leazas called Hikari Mi Blanc, who mysteriously disappeared after attending a prestigious academy in the capital of the country. Upon realizing that she's a cute girl, he accepts the job immediately and travels to Leazas along with Sill in order to find the missing girl, but he will soon find out that it's a case much deeper than it initially appears to be.
And so his Quest for Hikari begins...
